12 Data Science Hackathons to Test Your Skills

If you are passionate about technology, primarily coding and you have a desire to tackle business problems and innovate, you need a platform or environment that helps you with ideation, problem solving, collaborative learning, transformation in thinking. Hackathons are one of the best ways to go about it. Hackathon is a social coding event where computer programmers and other enthusiasts come together and solve interesting and real-world business problems by building a software program. Hackathon is a blend of words – hacker (skilled computer programmer) and marathon. Alternative names to hackathons include codefest, hack day etc.

Hackathons help you to put your coding skills to work and improve them. Through hackathons essentially one can learn new data science skills, build things and get hired as well. In addition to having a competitive element, hackathons provide an excellent platform to meet and collaborate with new people and also connect with experts in your industry. Along with all the learning, as a bonus mostly hackathons come with prize money or/and consideration for hiring.

Hackathons can happen virtually as well. Hackathon events are generally meant for a short period of time such as 16 to 24 hours, hence the participants are supposed to work rapidly and often work without sleep to achieve their task. But nowadays, we see good number of hackathons that run for a week to month as well (in the form of ‘coding contest or a hiring challenge’) 

What Is Data Science Hackathon?

Data science is one of the sought after fields due to its footprints in a wide array of applications including agriculture, healthcare, manufacturing, banking, advertising, retail, marketing etc. Visit here to attend the best online data science bootcamps . 

A data science hackathon is an event or hackathon where data scientists, machine learning engineers, MLOps engineers, data engineers and other data science enthusiasts participate, collaborate with one another and work on a data science business problem.
